  摘要：

  有机卤代硅烷是通过在铜或铜化合物催化剂和活性铝、铝合金或铝碳化物助剂的存在下，将金属硅与卤代碳氢化合物反应制备而成。该反应在250-400°C的温度下在搅拌槽反应器或流化床反应器中进行。这种创新的工艺缩短了Rochow反应中所需的激活时间，增加了对理想的二有机二卤代硅烷的选择性。因此，稳态被延长，硅的转化率提高，从而改善了反应性能。

  Single crystals of Li15Si4 and Li15-xAlxSi4 (x = 0.63(1)) were obtained from equilibrated melts with compositions Li100-xSix (x = 10, 15) and Li83Al13Si4, respectively, and isolated by isothermal centrifugation. Li15Si4 and Li14.37(1)Al0.63(1)Si4 crystallize with the Cu15Si4 structure type (I (4) over bar 3d, a(x=0) = 10.6322(9) angstrom, a(x=0.63(1)) = 10.6172(4) angstrom, Z = 4, T = 123 K). The incorporation of Al equally affects both crystallographically distinguished Li positions in the Li15Si4 structure. The replacement of about 4% of Li is firmly established by the refinement of single crystal diffraction data and NMR spectroscopy. The homogeneity range of Li15-xAlxSi4 was assessed as 0.4 < x < 0.8 from synthesis experiments using stoichiometric proportions of the elements. Differential scanning calorimetry studies confirm the metastable character of Li15Si4, decomposing exothermally at temperatures around 200 degrees C. However, the decomposition process of Li15Si4, is sluggish and appreciable rates are not observed before temperatures reach 400 degrees C. In contrast Li15-xAlxSi4 is thermodynamically stable. The decomposition temperature is at about 700 degrees C. It is speculated that the thermodynamic stability of Li15-xAlxSi4 is a consequence of the increased electron concentration, shifting the Fermi level to a pseudo-gap in the electronic density of states. Since metastable Li15Si4 plays an important role during electrochemical lithiation of a silicon anode, thermodynamically stable Li15-xAlxSi4 may have interesting properties as anode material in lithium ion batteries.
• Nonequilibrium state and lattice instability in supersaturated aluminum silicon solid solutions

  Nonequilibrium AlSi solid solutions have been prepared by means of thermal annealing (T similar to 1000 K) at high pressure (P similar to 4 GPa). This synthesis is possible due to the metallic character of silicon under high pressure which greatly enhances the solubility of silicon in aluminum. The study of these supersaturated AlSi solid solutions has enabled us to investigate the chemical destabilization of a crystalline lattice. We experimentally show by means of inelastic neutron scattering and low-temperature specific heat that, as the silicon concentration in the aluminum lattice is enhanced, transverse acoustic phonon modes are becoming softer. This corresponds to a dramatic decrease of the shear modulus. Using differential scanning calorimetry, the positive heat of silicon dissolution in aluminum is measured under normal pressure: Delta H=38 kJ/mole. We interpret it as being mainly due to the energy difference between a metallic bonding of silicon in aluminum compared to its usual covalent bonding after demixing. This large heat of dissolution appears as the major reason for the observed lattice instability. Comparison of our experimental results with corresponding effects observed in usual amorphous metals suggests that further increase of the silicon concentration would induce a structural transformation of this crystal if the silicon segregation could be prevented.
